With the development of imaging methods in wireless communications, enhancing the security and efficiency of image transfer requires image compression and encryption schemes. In conventional methods, encryption and compression are two separate processes, therefore an adversary can organize his attack more simply but if these two processes are combined, the output uncertainty increases. As a result, adversaries face more difficulties, and schemes will be more secure. This paper introduces a number of the most important criteria for the efficiency and security evaluation of joint image encryption and compression (JIEC) schemes. These criteria were then employed to compare the schemes. The comparison results were analysed to propose suggestions and strategies for future research to develop secure and efficient JIEC schemes.
